The Radium R3 63A Four Pole RCCB ‘AC’ Type with 100mA sensitivity is a premium electrical protection device designed to safeguard three-phase installations from earth leakage currents. It continuously monitors the current flow through all phases and the neutral line, automatically disconnecting power when leakage is detected to prevent electrical accidents and fire hazards.

The four-pole configuration provides comprehensive protection across three-phase systems, while the AC Type detection mechanism accurately identifies sinusoidal alternating current leakage, commonly produced by standard electrical loads such as lighting systems, heating equipment, and conventional appliances.

With a rated current of 63A and 100mA sensitivity, this RCCB is well-suited for medium-load electrical installations in residential buildings, commercial facilities, and light industrial setups, offering enhanced protection against leakage currents where higher safety standards are required.

Constructed using high-quality materials and designed for convenient DIN rail installation, the Radium R3 RCCB ensures reliable tripping, long-lasting durability, and robust protection for modern electrical distribution systems.
